Pressure-tested duct leak inspection. Aeroseal whole-duct sealing. Zoning systems. Full duct replacement when it’s the right call. The unsexy part of HVAC that has the biggest impact on your energy bills.
Your ductwork is the most overlooked part of your HVAC system. The average Cedar Grove home loses 25-40% of its conditioned air to leaky ducts — air you’re paying to cool that never reaches the room.
Pressure test (Duct Blaster) finds exactly where your ductwork leaks. We seal joints with mastic (the permanent sealant) and re-secure connections. Most homes recover 20-30% of cooling capacity after repair. $400–$1,800.
For systems with widespread small leaks, we use Aeroseal — an aerosolized polymer sealant that finds and plugs every leak from the inside. Reduces leakage by 60-95%. $1,800–$3,200 for typical home.
Truck-mounted negative-pressure cleaning of supply and return ducts using rotary brushes. Recommended every 5-10 years or after major remodel/fire/flood. $400–$700 for typical 2000 sq ft home.
Older Cedar Grove homes (pre-1980) sometimes have asbestos-wrapped ducts in basements or crawlspaces. We coordinate with licensed abatement contractors and install modern ductwork.
Two-story homes with one HVAC system often have hot-and-cold imbalance. Adding a zoning system (motorized dampers + zone controller) lets each floor maintain independent temperature. $1,800–$3,200 for two-zone retrofit.
For homes with significantly damaged, undersized, or improperly installed ductwork, replacement is the right call. We design Manual D-spec ductwork sized to your specific home and HVAC system. $4,500–$12,000+.
Most Cedar Grove homes built before 2010 have ductwork that leaks 25-40% of the conditioned air it’s supposed to deliver. That’s not a theoretical number — it’s what we measure with a Duct Blaster on the typical home we inspect.
If your AC produces 100 cubic feet per minute of cooling and 30% leaks into your attic before reaching the room, you’re paying for cooling that’s not actually cooling anything. Your system runs 30% longer, costs 30% more, and wears out 30% faster. For a typical Cedar Grove home with $1,800/year in HVAC operating costs, that’s $540/year in waste — $5,400 over 10 years — which is more than the cost of fixing the ducts.
We don’t sell ductwork upgrades unless we can demonstrate the leak with measurement equipment. Free duct leakage test included with any service call. If we find significant leaks, we provide a written report with measured CFM loss numbers, repair recommendations, and projected energy savings. You decide if the math works.
